Question

Sheleah and her family are planning a trip from Los Angeles, California to Melbourne, Australia. While booking her family's plane tickets, she notices on the itinerary that the airline is offering a sixteen hour straight flight from Los Angeles to Melbourne on a Boeing 747-8 Intercontinental Jet. In an effort to learn more about the capabilities of the Jet, Sheleah does a little research and stumbles upon the following graph and facts about the Jet's gasoline consumption.



The Boeing 747-8 Intercontinental Jet can carry approximately 422,000 gallons of gasoline, making it possible for the jet to travel 14,430 kilometers before needing to refuel.

Using the graph, approximate the Jet's average gas consumption, in gallons per hour, during the sixteen hour flight from Los Angeles, California to Melbourne, Australia. In your final answer, include all of your calculations.

Answer 1

Hello @james555 and Welcome to QuestionCove!

This seems to be the graph that was supposed to be included with your problem:

Answer 2

For your problem, we are looking for: "How much does the gallons decrease for every 1 hour that passes?"

Answer 3

Let's take the first two coordinate points for example

The points are
`(0, 422000)`
and
`(2, 369250)`

Where the format of the coordinate is: `(hours, gallons)`

So looking at those two points, how much did the `gallons` decrease?

Answer 4

whelp, the next step is going to divide that answer by 2

but if you come back and are still confused or stuck, just let me know! :)
